Definitions

  • the present invention relates to an antimicrobial composition for finishing textiles, yarns and fibers, comprising an organic antimicrobial component (K) and at least one metal salt component (M) and, if appropriate, solvents and further auxiliary components.
  • K organic antimicrobial component
  • M metal salt component
  • textiles contain microbiologically degradable material. They are often either wholly or partially made of microbiologically degradable fibers, for example cotton, cellulose (eg viscose and tencel), hemp, flax, linen, silk, acetate or wool.
  • textiles of synthetic fibers such as e.g. Polyester, polyacrylonitrile, polyamide (eg, aramid, Nomex, kevlar, polyamide 6, polyamide 6.6) or polypropylene are regularly colonized by bacteria, especially when treated with finishing agents, e.g. Plasticizers, water repellents, antistatic agents and / or binders, or to take up microbiologically degradable material during use, e.g. organic substances from the environment.
  • finishing agents e.g. Plasticizers, water repellents, antistatic agents and / or binders
  • composition or individual active substance which is equally suitable for all antibacterial equipments.
  • quaternary ammonium compounds for the antibacterial finishing of textiles is described, and substances of this class often cover a wide spectrum of germs with excellent effects, as Karl Heinz Walljunusser, Sterilization Disinfection - Preservation, 5th Edition, Georg Thieme Verlag Stuttgart, New York 1995, page 586 ff., Has long been known that quaternary ammonium compounds are bactericidal if at least one of the four substituents on the quaternary Nitrogen has a chain length of 8 to 18 carbon atoms, preferably one of 12 to 16 carbon atoms.
  • the other substituents may, for. B. straight or branched alkyl radicals or radicals with heteroatoms or radicals with aromatics. Frequently, one or more benzyl radicals are attached to the quaternary nitrogen in the molecule. Good results could also be found with quaternary ammonium compounds having two methyl groups, one n-alkyl group having between 10 to 18 carbon atoms and a 3-trimethoxysilylpropyl group.
  • Quaternary ammonium compounds have the positive property of being well soluble in water. This property is very suitable for the aqueous application in the industrial finishing process in the textile industry. At the same time, however, this property leads to such compounds being quickly washed off the textiles, since the adhesion to textiles is primarily possible by means of van der Waals forces and possibly also with ion pair bonds.
  • the quaternization can also be carried out with the Octadecyldimethylamin in methanol and then leads to a suboptimal in terms of antibacterial effect product.
  • the main disadvantage of this product is the solvent methanol, which, due to its properties in the textile industry, leads to massive restrictions in its application.
  • Textiles made of polyester have hitherto been equipped with a formulation containing the active ingredient dimethyl-tetradecyl- [3- (trimethoxysilyl)] - propyl-ammonium chloride, which is marketed as Sanitized T 99-19.
  • This is a 50% solution of the technical agent (salt) in methyltriglycol.
  • Methyl triglycol has the chemical formula CH 3 (OCH 2 CH 2 ) 3-OH.
  • the likewise known product Aegis AEM 5772/5 is an approximately 5% aqueous solution of the active ingredient dimethyl-octadecyl-fS- rimethoxysily ⁇ -propylJ-ammonium chloride.
  • the more concentrated active ingredient dissolved in methyl alcohol is also available.
  • the equipment of the textiles were preferably done by padding.
  • these textiles are tested by means of a count test according to the method JIS L 1902: 2002 or according to ASTM E 21-49, they show an excellent antibacterial effect.
  • These known products are found, for example, on textiles made of cellulose fibers reactants with which they can react chemically and can form a stable covalent bond. On such textiles, the antimicrobial finish is durable. On the other hand, on polyester or polyamide there are too few reactants to bind such products permanently. If these textiles are washed, this antibacterial effect usually disappears almost completely after a few washing cycles.
